LG Dryer Thermistor Assembly Parts — Models & Compatibility

If your LG dryer is taking forever to dry a normal load, stopping mid-cycle for no reason, or throwing random error codes, the thermistor assembly is a prime suspect. This temperature sensor tells the control board exactly how hot the drum is getting — when it fails or gets coated with lint residue, your dryer either overheats or never gets hot enough. The 6323EL2001B thermistor assembly (also sold as AP4441539 and PS3529026) fits over 100 LG and Kenmore Elite dryer models from the DLE and DLEX series.

Is This the Right Part for Your Model?

Check your dryer's model number before ordering. On most LG dryers, you'll find the model/serial tag inside the door opening along the front panel rim, or on the back panel near the vent connection. The thermistor fits DLE and DLEX electric models, plus DLGX gas models — verify your exact model against the compatibility list below. If your model number starts with DLE0, DLE2, DLE3, DLE5, DLE6, DLE7, DLE8, DLE9, DLEX4, DLEX7, or DLGX4, you're likely in the right place.

About This Replacement Thermistor Assembly

The thermistor is a small temperature-sensing component mounted near the heating element or exhaust duct. It sends resistance readings to the control board, which uses that data to regulate drying temperature and cycle timing. When it goes bad, you'll notice clothes staying damp after a full cycle, the dryer getting abnormally hot to the touch, or cycles shutting off early with error messages on the display. One of the most common causes of thermistor failure isn't age — it's lint buildup. A thick coating of lint and debris on the sensor prevents it from accurately reading drum temperature, causing the control board to make bad decisions about heating and timing. If you've been running your dryer with a clogged lint screen or restricted exhaust vent, the thermistor takes the hit first.

Replacement Part Numbers

The 6323EL2001B replaces several discontinued or superseded part numbers. If you're cross-referencing an old service manual or parts diagram, these numbers all refer to the same thermistor assembly: AP4441539, PS3529026, 6323EL2001H, and 1268206. LG updated the part number over the years, but the physical component and connector remained the same across model generations.

What Causes Thermistor Failure?

Besides lint accumulation, thermistors can fail from normal electrical wear over thousands of cycles. The constant heating and cooling causes tiny cracks in the resistor element, throwing off the resistance curve the control board expects to see. If your dryer has been stopping mid-cycle with no error code, or the display shows cryptic codes like TE1 or TE2, the thermistor is either reading out of range or not responding at all. Don't ignore these symptoms — running a dryer with a bad thermistor can overheat wiring and damage the heating element or control board.
